Thanks for the tip.One more reason a tank can go cloudy is by the introduction of a contaminant that the bacteria can use as a nutrient. Unwashed dirty hands, liquids, and chemicals are a few examples of sources of nutrients. Please note that in a filtered and aerated aquarium, the actual bacterial bloom is in itself not harmful to the fish.

Durbkat...when you make accusations against a person's fishtank..sometimes it's helpful (and looks less condenscending) if you post a link, or some sort of logical explination, explaining why you posted what you think is the problem.
Caves look nice in a tank, you can make them out of coconut shells, or bits of slate leaning onto another rock. Caves are good for places to hide for the fish and chill out.
What about a small bit of bog wood or something. You could try rearanging the plants to the back that would give some more swimming room at the front of the tank. And room to put a feature ornament.
